[Art.] 100. [Alternate Methods of Proposing Amendments.] Amendments to this constitution may be proposed by the general court or by a constitutional convention selected as herein provided.

(a) The senate and house of representatives, voting separately, may propose amendments by a three fifths vote of the entire membership of each house at any session.

(b) The general court, by an affirmative vote of a majority of all members of both houses voting separately, may at any time submit the question "Shall there be a convention to amend or revise the constitution?" to the qualified voters of the state. If the question of holding a convention is not submitted to the people at some time during any period of ten years, it shall be submitted by the secretary of state at the general election in the tenth year following the last submission. If a majority of the qualified voters voting on the question of holding a convention approves it, delegates shall be chosen at the next regular general election, or at such earlier time as the legislature may provide, in the same manner and proportion as the representatives to the general court are chosen. The delegates so chosen shall convene at such time as the legislature may direct and may recess from time to time and make such rules for the conduct of their convention as they may determine.

(c) The constitutional convention may propose amendments by a three fifths vote of the entire membership of the convention.

Each constitutional amendment proposed by the general court or by a constitutional convention shall be submitted to the voters by written ballot at the next biennial November election and shall become a part of the Constitution only after approval by two thirds of the qualified voters present and voting on the subject in the towns, wards, and unincorporated places.
